When you're talking about using a lot of disks, that's going to be true for any disk subsystem that you're trying to get a lot of performance out of. The old rule was that if you had more than four disks per channel, you were probably hitting saturation. I don't know if that specific rule-of-thumb is still valid, but I'd be surprised if disk controller performance hasn't roughly kept up with disk performance over time. -- Brad Knowles, <brad_at_stop.mail-abuse.org> "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -- Benjamin Franklin (1706-1790), reply of the Pennsylvania Assembly to the Governor, November 11, 1755 SAGE member since 1995.
